           Summary: out of memory

          Platform: Other
        OS/Version: Other

          Severity: Critical
          Priority: Other
         Component: Connector:Coyote JK 2
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: eresha@bigpond.com


Hi,

I am having "out of memory" problems. Our configuration is like this.

webserver->firewall->tomcatserver(LAN)

The out of memory problem only occurs between the webserver/tomcatserver - ie 
the coyote jk2 connector. I can still access and use tomcat internally from our 
LAN using the Coyote HTTP Connector. THis error is intermittent and occurs 
sometimes. However, when it does occur we cannot access tomcat via our external 
(internet) users until we restart tomcat.

Refer log below:
